  • Controlling the number of on-grid multiple photovoltaic inverters to improve their conversion efficiency

    Two experimental PV-grid connected systems of 8.8 kWp and 36 kWp rating have been designed, installed and interfaced with Abu Dhabi utility grid. The PV arrays of both systems are interfaced with the grid via single phase grid-tied inverters. The inverters are installed in three separate groups that each injects 50 Hz electricity into one phase of the utility grid at the 0.4 kV level. The main ...

  • Solar`s Time to Rise and Shine.

    Photovoltaic efficiency records are being shattered, thanks to recent advances in materials science. Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. The simulator flashed a 2.5 millisecond pulse of light, and 19 mirrors reflected the ...
